The experimental results show that pore structure has more influence on the performance of ACF electrode than that of specific surface area for ACF material.

Fig.7 Ca2+ Electrosorption capacity of ACF electrode. 3.3 Effect of pore structure on Ca2+ electrosoption capacity of ACF electrode ACF1 and ACF4 were selected to investigate the effect of pore structure on Ca2+ electric adsorption capacity, and the results are shown in Fig.7.
Therefore, compared with surface area, more attention should be paied to pore structure of ACF when preparing the ACF electrode.

This paper will redefine the attribuation of high-Alumina clay ore by analysing its differences and similarities with refractory clay minerals and bauxite mines in mineralogy, rock chemistry as well as physical structure, and present some advice on its comprehensive usage aiming at the existed problems in comprehensive development and utilization.
But by contrastive analysis of high-alumina clay and refractory clay reveals the dramatic differences between them in mineral component, petrochemistry and physical structure.
In physical structure, high-Alumina clay mineral is complex, and it often presents lentiform, brecciform and dense block.
From the natural types of view, bauxite ores are partitioned for the structure, color and main composition of aluminum mineral.
It can be divided into earthy (rough shape), compact shape, lenticular, oolitic, clastic, brecciated, sand-like, almond shaped, vesicular bauxite according to the structure.

The obtained cobalt hydroxide nanodiscs are of single-crystalline hexagonal structure with well-defined planes.
Introduction In recent years, controlling the morphology and structure of inorganic nanomaterials has intrigued increasing interest because the physical and chemical properties of nanomaterials depend not only on their composition but also on their structure, such as phase, shape, crystallinity, size, and size distribution.
Cobalt oxide nanoplates, nanodiscs and nanoparticles have been synthesized by different methods [6-7], but those methods could not control the morphology or structure of cobalt oxide.
From the SAED pattern, it can be revealed that the cobalt oxide nanodiscs are of single crystalline structure and can be indexed as a hexagonal structure with an incident electron beam parallel to the [001] orientation.

The absorption of P3HT film shows a vibronic structure with resolved peaks at 520 nm and 550 nm.
This feature is related to ordering of the P3HT chain forming lamellae structure [10].
ZnO-NP has wurtzite crystal structure as compared to JCPDS 36-1451.
This XRD pattern confirms that P3HT has crystalline structure so called lamellae structure which is in line with UV-Vis spectrum of thin film.
We also have studied optical, crystal structure and surface morphology of thin films of P3HT, PCBM, ZnO-NP and their blends.

Unfortunately, carrier bound enzymes have mass non-catalytic structures which decrease enzymes volume thus dilute activity.
This may occur with folded structure reversible unfolding.
With incubation time increase, majority aggregate was cross-linked and the structure would be more stable and rigid, activity increased rapidly.
